中文摘要：
利用大葱生物膜内外有别的结构特性模拟生物矿化过程，在室温下同步诱导合成出颗粒状和球状两种不同形貌的硒化汞材料，前者尺寸约为200nm的大纳米颗粒，该产物可能是由尺寸约30nm的小纳米粒子组装而成；后者尺寸约为3μm的高度致密的带花边的实心圆球，该产物可能是自发生长或由直径约1μm的小球组装而成．其结构均为立方相，晶格常数为0．608nm．通过紫外可见光谱（UV—Vis）和荧光光谱（Fluorescence，FL）对产物的光学性质进行了研究．初步探讨了硒化汞的合成机理．
英文摘要：
Mercury selenide microsphere and nanoparticle were synchronously synthesized with the green Chinese onion as the living biotemplate. The result indicates that the former large spheres with the diameter of 3 μm are possibly self-vegetal or packaged by those with that of 1 μm, and the latter with the size of 200 nm are possibly packaged by the nanoparticles with the size of 30 nm, and both of them have a cubic structure with a cell parameter is 0. 608 nm. Their optical properties were investigated by both UV-Vis and FL spectra. In addition,possible mechanisms are investigated.
